SERVEP P2P NETWORK SYSTEM AND METHOD FOR ROUTING AND TRANSFERING THE RESOURCE KEY ASSIGNMENT THEREOF

摘要

A server, a P2P network system, a method for routing, and a method for transferring resource key assignment are provided. The server comprises a routing processing module and a storage module connected therewith. The P2P network system comprises a structured P2P network and a server configured therein. The server routes the searching node to the node storing the resource key assignment based on the stored information, to thereby achieve a quick route. The method for routing is realized by searching for the node storing the resource key assignment via the server. Therefore, it merely takes two hops, i.e., the server and the node storing the resource key assignment, for the node to find the resource key assignment in search. The method for transferring resource key assignment is realized by duplicating or deleting, when the node is joined or is leaving, the resource key assignment under the charge of the node, and notifying the server, in order to ensure that the node information in the storage module is updated in time, and to ensure that the node may search out the node storing the resource key assignment promptly and accurately.
